Description

Sliding structure for railway passenger station reconstruction and extension project and construction method thereof

Technical Field

The application relates to the technical field of constructional engineering, in particular to a sliding structure for railway passenger station reconstruction and extension engineering and a construction method thereof.

Background

In a certain railway passenger station reconstruction and extension project, two railway tracks are special channels for freight trains, the frequency of passing the trains is very frequent, and the trains can not be stopped completely. In the air above the busy railway track main line, a waiting hall of a high-speed railway station is constructed, specifically, a large concrete floor slab is constructed in the air above the railway track as a framework structure of the waiting hall. The key point is how to build the concrete floor under the condition that railway trains pass below. In the engineering field, the construction of concrete floor slabs needs to firstly erect a template support system, then bind floor slab reinforcing steel bars and pour concrete. How to avoid the influence on the railway train passage in the process of erecting a template support system and building a floor slab is the key and difficult point of engineering construction.

The method is generally characterized in that a bailey truss platform is erected above a non-stop railway track, on one hand, the bailey truss platform can be used as a basic platform of a template support system, and on the other hand, the bailey truss platform can prevent electricity from being transmitted by an overhead electrified contact net of the railway track. However, the bailey truss platform and the construction method for erecting and dismantling the bailey truss platform are inconvenient. The Bailey truss platform is formed by assembling a plurality of Bailey beams, and a single Bailey beam is heavy, so that the Bailey truss platform is assembled on site one by one after needing to be hoisted in place one by adopting hoisting machinery at a building site. In addition, in the case of frequent train passage, it is necessary to assemble the bailey beams to form the bailey frames at the gaps of train passage (i.e., when no train passes). The method for constructing the floor slab structure according to the Bailey truss platform has low efficiency and is very slow, and is easy to generate larger safety risk.

After the construction of the floor slab of the waiting hall is finished, namely after the concrete pouring of the floor slab is finished, the bailey truss platform needs to be dismantled. As a whole concrete structure floor slab is built above the bailey truss platform, and a passing railway train is arranged below the bailey truss platform, the bailey truss platform is difficult to dismantle. When no train passes through, the Bailey truss is disassembled into a single Bailey beam, the Bailey beam is dragged by a dragging machine at one side of a dismantling place, and the Bailey beam is drawn out from the upper space of a railway track to the side without the railway track. The demolition method also has the defects of low demolition efficiency, excessive influence factors and easy occurrence of safety accidents.

Therefore, on the basis, a construction method which is safer and has higher work efficiency is researched. On one hand, the problem of work efficiency of building a formwork support system foundation platform is solved, and on the other hand, the problem of safety of dismantling the formwork support system foundation platform is solved.

And a sliding chute mounting step S4, wherein one sliding chute 41 is hoisted and mounted on the support nodes 10 and the two auxiliary platforms 30 which are arranged in a straight line through the hoisting station 300, and the other sliding chute 41 is hoisted and mounted on the support columns 20 and the two auxiliary platforms 30 which are arranged in a straight line through the hoisting station 300.

And a plate-shaped supporting structure installing step S5, arranging two sets of sliding mechanisms on the bottom surface of the plate-shaped supporting structure 50, and lifting and placing the plate-shaped supporting structure 50 in the two sliding chutes 41 through the lifting station 300 by setting the two sets of sliding mechanisms at the same distance from each other as the distance from the supporting node 10 to the supporting column 20, so as to form a newly reconstructed and expanded concrete floor and a supporting system of the scaffold.

And a step S6 of installing templates and scaffolds, wherein a full scaffold and template system is erected on the support system, and concrete is poured into the template system to form a new concrete floor connected with the original railway station 100, so that the reconstruction and extension of the original railway station 100 are completed.

It should be noted that the crane station 30 should travel in all steps to ensure that the original railway station 100 is not damaged.

Correspondingly, after the reconstruction and extension project is completed, the concrete working process of disassembling the sliding structure is as follows:

and a formwork and scaffold dismantling step S7, namely dismantling the formwork system through other auxiliary tools such as a forklift and the like, and dismantling the full scaffold. Since the structure after the extension is located above the sliding mechanism, the disassembly process does not affect the railway train normally running on the railway track 200.

A plate-shaped support structure disassembling step S8, where the first pushing mechanism 55 pushes and translates one of the plate-shaped support structures 50 to one of the auxiliary platforms 30 along the first direction, the second pushing mechanism 55 pushes and translates the other plate-shaped support structure 50 to the other auxiliary platform along the second direction, the beam-plate structures 50 'of the plate-shaped support structures 50 are disassembled on the auxiliary platforms 30 sequentially, and the disassembled beam-plate structures 50' are removed by the crane station 300. It will be appreciated that the first urging mechanism 55 should be at a distance from each urging that ensures that at least one beam and slab structure 50 'can be disassembled, and correspondingly, the second urging mechanism 56 should be at a distance from each urging that ensures that at least one beam and slab structure 50' can be disassembled.

In the chute disassembling step S9, the chute 41 is hoisted and moved by the hoisting station 300, and the chute 41 is a multi-stage chute body and can be disassembled in stages in sequence.

The auxiliary platform disassembling step S10 is to disassemble the auxiliary platform 30 through the crane station 300, sequentially disassemble the auxiliary support plate 33 on the auxiliary platform 30, and sequentially disassemble the first auxiliary support column 31 and the second auxiliary support column 32. The first auxiliary supporting column 31 and the second auxiliary supporting column 32 in the auxiliary platform 30 are also located at two sides of the width direction of the railway track, and the normal operation of the railway is not affected by the disassembly of the auxiliary platform.

And a support node and support column disassembling step S11, wherein the support column 20 and the support node 10 are disassembled by lifting the lifting station 300, and the support column 20 and the support node 10 are respectively positioned at two sides of the width direction of the railway track, so that the normal operation of the railway is not influenced by the disassembling of the support column 20 and the support node 10.

Of course, the order of disassembling the auxiliary platform disassembling step S10, the support nodes, and the support column disassembling step S11 is not limited, and the support nodes and the support columns may be disassembled first, and then the auxiliary platform may be disassembled.

In summary, the sliding structure for the railway passenger station reconstruction and extension project and the construction method thereof provided by the embodiment are respectively located on two sides of the width direction of the railway track through the supporting nodes and the supporting columns, and form a template supporting system with the slidable plate-shaped supporting structure for the railway passenger station reconstruction and extension project, and the sliding structure is simple in structure, high in erection efficiency and high in safety.
